Note
ECG performance during MRI scanning can be further improved by
modifying scan sequence parameters at the MRI console. Changing
any of these parameters directly alters image quality so precaution
must be taken to not overwhelmingly affect the desired image
characteristics:
• Increase TE (Echo Time)
• Increase TR (Repetition Time)
• Increase TI (Inversion Time)
• Increase / change the imaging plane (for example, sagittal to
axial)
• Turn off fat suppression
• Decrease the PNS level
• Decrease the gradient strength
